Specification of Letters Patent.

Patented Sept. 30, 1913.

Application led November 29, 1912. Serial No. 4734,188.

To all whom t may concern Y Be it known that I, WILLIAM E. PARK,

M. D., acitizen of the .United States, residing at Rockford, inV thecounty of Winnebago and State of Illinois, have'invented' certain newand useful Improvements in Refrigerators; and I 'do hereby declare thefollowing to be a full, clear, and exact description of the invention,suchV as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to portable receptacles for containing samples ofmilk collected during a tour of inspection of a health officer or a likeperson.

The invention consists in an outer receptacle within which is containedrequisites for the sanitary reception and storage of samples of milkcollected for the purpose of chemical or bacteriological examinations.

The invention further consists in means for refrigerating the articlesstored in the receptacle, whereby chemical action within the milk isprevented.

The invention further consists in novel details' of construction whichwill be hereinafter more clearly set forth in the following specicationand claims.

In the accompanying drawings, wherein is shown the preferred form of myinvention, Figure 1 is a longitudinal sectional view partly broken awayof my improved apparatus, and, Fig. 2 is a longitudinal sectional viewthrough the inner refrigerator.

Referring to the drawings, wherein like reference numerals designatecorresponding parts throughout the several views, 1 indicates an outercasing having a hinged cover 2 carrying a suitable handle 3 tofacilitate transportation. Within the casing 1, upon the oppositelongitudinal sides thereof, are provided strips f1 for supporting inspaced relation in the casing, a refrigerating compartment 5. At one endof the casing 1 is left sufficientspace for analcohol lamp 6 and the tworeceptacles 7 and 8, for a purpose which will be hereinafter moreclearly set forth. The refrigerating compartment 5 is preferably formedrectangular in shape with an open upper end adapted to be closed byahollow cover 9, hinged at one end to the end wall of the compartment.Adjacent the bottom of the interior surface of the side walls is secureda plurality of bracket arms 10, vadapted to support in spaced relationfrom the ioor of the compartment, a tray plurality 11, having anupwardlyextending handle 12 secured Vcentrally thereof. The spacebetween the tray 11 and the floor of the compartment 5 is adapted to befilled with ice, as shown. Arranged upon the tray11 is a of samplecontaining bottles 13 having sanitary coverslfl secured thereover bymeans of cords or the like 15. The hollow. vcover 9 of the refrigeratingcompartment .is provided with longitudinal side and bottom walls, aperforate hinged end 16, and a hinged door 17 at the opposite end,normally held in closed position by the spring 18. To facilitatedrainage of the melted ice contained in the hollow cover 9, the bottomof said compartment is inclined toward the hinged end of the compartmentand formed of sufiicient length so as to pro-ject into a drain passage19 formed at the end of the compartment by means of the partition 20.

On collecting a sample of milk, the operator removes the cover from thebottle and passes the flame from the alcohol lamp 6 over the mouth ofthe bottle to thoroughly sterilize the latter. The sample of milk isthen poured into the sterile bottle and the paper tied over the neck ofthe bottle with the string, as before, an inner stopper being disposedin the mouth of the bottle before the outer cover 14; is placedthereover if such precaution is thought necessary. The receptacle 7 `isemployed for containing fuel for the lamp 6 and the receptacle 8 is forthe purpose of containing sterile gauze to be used in cleaning thebottles or the thermometer employed for taking the temperature of themill The water resulting from the melting of ice within therefrigerating compartment 5 may be drawn off, at convenient times, byopening the valve in cock 21 connected to .the lower portion of thecompartment. The bottom of the casing 1 is provided with an openingfitted with a funnel 22 into which the water discharged from the cock 21Hows, and is emptied outside of the casing.

From the foregoing, lit will be seen that I have provided an efficientand convenient means, and also an entirely sanitary one, for collectingand storing samples of milk until such time when it is convenient tomake tests or examinations thereof.

What I claim is 1. The herein described refrigerator comprising acasing, a hollow cover hinged thereto, thebottom of said cover beinginclined from the free to the hinged end, a perforate end Wall for thehinged end of said hollow cover, and a door hinged to the free end ofsaid cover.

2. The herein described refrigerator oomprising a easing,y a hollowcover hinged thereto, a partition in the end of said cas-V ing forming apassage between the end wall of said Casing and said partition, thebottom of said hollow Cover being inclined from the free to the hingedend thereof and the. lowermost end thereof extending into said pas sage,and a perforate end in the hinged. end of said cover. v

3 The herein described refrigerator comprising a casing, a hollow coverhinged thereto, the bottom of said coverfbeing inclined from the free tothe hin ged end thereof, a' door hinged to the free end of said covenapartition in said easing forming a of said casing, the loWermost end ofthe botwithin said passage, and a removable tray support above thebottom of said' casing.

In testimony whereof I. have Signed myV name to this specification inthe presence of two subsribing witnesses.
